HAIR-WAVING DEVICE.

Application led .Tuly 28, 1925. Serial No. 46,512.

My invention relates to improvements in a hair waving device for producing what is known as a permanent wave. The object of my invention is to provide a waving device in which theweight is greatly reduced and in which the size is also produced, relatively to those now in use; a further object of my invention is to embody the electric heating element Within the core member upon which the hair is wound instead ot surrounding the coil of hair with a `sleeve having a heating element therein, as is now the practice; a still further object of my invention is to provide a core containing the electric. heating element with a detachable cable connector upon one end thereof and yto construct said parts suiiiciently small in diameter that the paper or ber protecting tube, now used for encasing the coil of hair may be readily slipped over the end of the core carrying one member of the cable connector and thus avoid the necessity of using a tube which is any larger in diameter than those now in use; and a still further object of my invention is to provide a novel method of waving hair by which better results and more permanent Waving is obtained.

Permanent hair waving machines such as now in general use employ a large number of waving devices for the separate strands of hair, therefore any reduction in the weight and size of the separate waving devices is of great advantage and an advancement in the art.

Referring to the accompanying drawings: Fig. 1, isa View in elevatlon of my improved Wavin device showing a coil of hair thereon and s owing the heat retaining tube surrounding the hair, said tube beingshown in section; Fig. 2 is an enlarged transverse section on line 2-2, Fig. 1; Fig. 3, is an enlarged longitudinal sectional view of the core containing a heating-element and showing one member of a cable connector secured upon said core, and Fig. 4, is a view in elevation of the heat retaining tube drawn on the same scale as Fig. 3, showing that said tube may be passed over the connector and core.

Referring to the drawing in which like reference characters refer to like parts, 5 represents the core of the hair waving device which is of hollow construction and preferably consists of a metal tube. At one end ofthe core 5 is formed, or secured, a fastening device 6, having a cord retaining slot 7 formed therein, similar in construction to those now in use upon the solid core rods upon which the hair is wound.

An electric heating unit 8, of any well known type, is mounted Within the core 5 and is adapted for heating the core 5 throughout its entire length. Upon the opposite end of the core 5 from that at which the YI'iastening device 6 is located, is secured the member 10 of a cable connector having a counter part 12 with which it may be readily attached and detached. The connector member 10 is provided with contact pins 13 and 14 which are electrically connected with the heating unit 8 in the usual manner. The connector member 12 is adapted to receive the pins 13 and 14 and complete the electric circuit from the cable or wires 16, with the heating unit 8.

A tube 20 of fiber and asbestos or any other heat retaining material is provided for encasing the coil of hair and said connector member 10 is of suiciently small diameter that the tube 20 will readily pass over said member 10, when itis detached from the member 12.

The core 5 is covered with a fabric 22, consisting preferably of a sheet of flannel prepared in the usual manner with borax and oil as now generally used in connection with hair waving devices.

The operation of my novel hair wavin device is as follows: a cord 25 is tied aroun a strand of hair 30, close to the scalp, as shown in Fig. 1, and the cord is secured in the notch7 formed in the 'fastening device 6. The strand of hair 30 is tightly coiled around the core 6, having the fabric 22 thereon, and the outer end of the strand 30 is secured by several turns 26 of said cord 25. The retaining tube 20 is passed over the connector member 10 and over the coil of hair, as shown in Fig. 1. kThe connector members 10 and 12 are attached so as to complete the circuit including the heating unit 8.

By locating the heating unit in the core 5 around which the strand of hair is wound, I provide a method by which the hair may be more tightly wound around the fabric 22 and by locating the heating unit within the fabric and coil of hair, the heat must pass through the 'fabric to the coil vof hair. The tube 20, which is located outside of the heatingrunit, retains the heat around the coil of hair, thus producingl a more effective waving of the hair than as been heretofore f .i maaien obtained in hair Waving devices, in which the heating unit is located around the outside surface of the tube containing the hair; the latter being wound around. a center core Which is not heated. The unheated metal core tends to draw the heat out of the coil of hair, Whereas in my novel method the heated core drives the heat through the hair from the center oi. the coil outwardly and the heat retaining tube encases both the coil of hair and the heating unit.

ll claim:

l. A device for heating a coil of hair in the practice of permanent hair waving, comprising a tube for containing the coil of hair7 a core, a layer of hair waving material immediately surrounding the core around which the hair is coiled and an electric heating unitrwithin said core.

2. A. device for heating a coil of hair in the practice of permanent hair Waving,coin prising a tube Jfor containing the coil of hair, a rigid core, a layer of absorbent material surrounding the core around which layer the hair is coiled, and an electric` heating unit `Within said core.

3. lin a device ot the character described,

a core adapted to have a strand of hair coiled thereon having means at one end of said core adapted to be secured to the strand of hair adjacent to the scalp, an electric heating unit in said core, a heat retaining tube adapted to encase the coiliof hair when wrapped around said core, a connector member adapted for detachably connecting electric conductors to said heating unit located at the opposite end of said core, and said member being smaller in diameter than said tube whereby said tube may bepassed over said member after the hair is coiled upon the core.

Lt. The method of Waving hair comprising coiling the hair around a heating core covered With a permanent hair Waving layer of chemically prepared fibrous material, en- 45 casing the coil of hair in a heat retaining tube, and applying the heat to said core for producing heat Within the fibrous material thereby forcing the chemically saturated moisture outwardly from said fibrous Inaterial through the coil oit hair.
